GRAPHENE_POINT_INIT

#define GRAPHENE_POINT_INIT	(		_x,
			_y )   (graphene_point_t) { .x = (_x), .y = (_y) }

GRAPHENE_POINT_INIT: @_x: the X coordinate @_y: the Y coordinate

Initializes a graphene_point_t with the given coordinates when declaring it, e.g:

|[ graphene_point_t p = GRAPHENE_POINT_INIT (10.f, 10.f); ]|

Since: 1.0

GRAPHENE_POINT_INIT_ZERO

#define GRAPHENE_POINT_INIT_ZERO   GRAPHENE_POINT_INIT (0.f, 0.f)

GRAPHENE_POINT_INIT_ZERO:

Initializes a graphene_point_t to (0, 0) when declaring it.

Since: 1.0
